1 Safety instructions

1.1 Designated use

• The measuring device described in these Operating Instructions is to be used only for

measuring the flow rate of liquids in closed pipes, e.g.:

– Ultrapure water with low conductivity

– water, wastewater etc.

• As well as measuring the volume flow, the sound velocity of the fluid is also always measured.

Different fluids can be distinguished or the fluid quality can be monitored.

• Any use other than that described here compromises the safety of persons and the entire

measuring system and is, therefore, not permitted.

• The manufacturer is not liable for damage caused by improper or non-designated use.

1.2 Installation, commissioning and operation

• The measuring device must only be installed, connected, commissioned and maintained by

qualified and authorized specialists (e.g. electrical technicians) in full compliance with the

instructions in these Brief Operating Instructions, the applicable norms, legal regulations and

certificates (depending on the application).

2 Installation

2.1 Installation conditions

2.1.1 Dimensions

For the dimensions of the measuring device, see the associated Technical Information on the

CD-ROM.

Mounting location

Correct flow measurement is possible only if the pipe is full. Entrained air or gas forming in the

pipe can result in an increase in measuring errors. For this reason avoid the following mounting

locations in the pipe:

• Highest point of a pipeline. Risk of air accumulating.

• Directly upstream of a free pipe outlet in a vertical pipeline.

A0001103

Fig. 1: Mounting location

Down pipes

Notwithstanding the above, the installation proposal below permits installation in an open down

pipe. Pipe restrictions or the use of an orifice plate with a smaller cross-section than the nominal

diameter prevent the pipe from running empty while measurement is in progress.

Orientation

Vertical

Recommended orientation with upward direction of flow (View A). With this orientation,

entrained solids will sink and gases will rise away from the sensor when the fluid is stagnant.

The piping can be completely drained and protected against solids buildup.

Installation Proline Prosonic Flow 91W

6 Endress+Hauser

Horizontal

In the recommended installation range in a horizontal installation position (View B), gas and air

collections at the pipe cover and problematic deposits at the bottom of the pipe have a smaller

influence on measurement.

Inlet and outlet runs

If possible, install the sensor well clear of fittings such as valves, T-pieces, elbows, etc. If several

flow obstructions are installed, the longest inlet or outlet run must be considered. Compliance

with the following inlet and outlet runs is recommended in order to ensure measuring accuracy.

3 Two pipe bends in different directions

2.2 Preparatory steps prior to installation

Depending on the conditions specific to the measuring point (e.g. Clamp On, number of

traverses, fluid etc.), a number of preparatory steps have to be taken before actually installing the

sensors:

1. Using the conditions specific to the measuring point, determine which installation

distances are necessary for installation.

2. Determine the values for the requisite installation distances.

A number of methods are available for determining the values:

– Local operation of the device

– FieldCare (operating program) procedure explained in the Operating Instructions on

the CD-ROM

– Applicator (software) procedure explained in the Operating Instructions on the

CD-ROM

3. Mechanical preparation of the "Clamp On" holders for the sensors:

– Premount the strapping bands (DN 50 to 200 / 2 to 8") or (DN 250 to 4000 / 10 to 160")

or wire the device while it is connected to the power supply. Failure to comply with this

precaution can result in irreparable damage to the electronics.

• Risk of electric shock. Connect the protective ground to the terminal on the housing before

the power supply is applied.

! Note!

To ensure correct measuring results, route the cable well clear of electrical machines and

switching elements.

! Note!

There is a wiring procedure for the sensor DN50–DN4000 and DN15 to 65 respectively.Cable

and cable entry are distinct different for the two sensor connection types.

4.1.1 Procedure

! Note!

The outer shield of the sensor connecting cable (triaxial cable) is grounded by a ground disk in

the cable feedthrough (A). This grounding is absolutely essential to ensure correct

measurement.

1. Unscrew the cover (c) of the cable gland (A). Remove the rubber seal (d).

2. Guide the sensor connecting cables (a, b) through the cover of the cable gland.

3. Guide the sensor connecting cables individually through the ground disk in the cable gland

holder (g) and into the connection compartment.

4. Plug in the connectors of the sensor connecting cables.Left sensor upstream (a), right sensor downstream (b).The connector engages with a click when correctly plugged in.

5. Spread the rubber seal (d) along side slits (e.g. using a screwdriver) and fix the cables in

place appropriately. Push up the rubber seal in the cable gland until the sensor cable

sleeves are pressed against the ground disk.

6. Close the cover of the cable gland (c) so that it is tight.

7. In the connection compartment, fix the two sensor connecting cables in place in the

holder (i) provided.

Procedure

1. Screw the cable gland (5) into the transmitter housing.

2. Guide the sensor connecting cables through the cable gland cover (6).

3. Threat the sensor connecting cables into the transmitter housing. Align the outer end of the rubber grommet (3) with the end of the cable gland (5)

/grounding mechanism (7). This ensures that the cable entry will be a) tight and b) the cable is correctly grounded to the transmitter housing at the internal contact

point (4) once tightended.

An external inspection is not possible, so it is important to follow this instruction.

4. Tighten the cable gland cover (6) clockwise.

! Note!

The red marked cable is sensor "up"; the blue marked cable is sensor "down".

! Note!

The cable gland can be released from the cable by unscrewing and removing tha cable gland

cover. Then retract the grounding mechanism (7) with pair of pliers. The retraction of the

mechanism does not require strong force (strong force might destroy the screen). It might be

required to lift the internal hooks of the grounding mechanism out of a locked position by

pressing the grounding mechanism further forward by turning the cable gland clockwise.

Remove the cable gland cover again. Then retry to retract with the pair of pliers.
